ABSTRACT

BPV-2 infection can cause bladder infections in cattle that, when associated with bracken fern consumption, can progress to cancerous bladder tumors and also present as bovine enzootic hematuria (BEH). This study aimed to evaluate the prolonged natural BPV-2 infection in the blood and urine of cattle, excluding bracken fern consumption. Thirteen Girolando papillomatosis-affected cattle with no bracken fern contact history were monitored for 20 months. Blood, urine, and wart samples were collected for BPV-2 detection and clinical laboratory analyses. All animals showed the presence of BPV-2 in papillomas and blood, and 92.85% showed BPV-2 in urine, suggesting viral dissemination in the urinary tract. Despite all animals being infected with BPV-2, none showed BEH signs during the study. Thus, it was observed that BPV-2 infection alone didn't induce BEH over 20 months, implying a complex interaction with environmental factors or genetic predisposition. This underlines bracken fern consumption's critical role in urinary bladder carcinogenesis. The study underscores BEH's pathogenesis complexity, advocating longitudinal studies to comprehend BPV-2's role fully.

ABSTRACT

Background: The male effect is an attractive strategy to increase herd production by concentrating mating events and deliveries and further allowing the adoption of genetic improvement programs. It holds similar efficiency to those chemically based estrous synchronization methods, but has the advantage of being a natural method. The work was aimed to evaluate the influence of male effect on estrous induction and synchronization, pregnancy and prolificacy of nulliparous Santa Inês and Morada Nova ewes raised in Semiarid and Zona da Mata regions of Pernambuco state. Materials, Methods & Results: Santa Inês (n = 80) and Morada Nova (n = 80) females, with age from 11 to 12 months, after being evaluated and selected, were identified with plastic ear tags, weighted and maintained isolated from males, during 30 days before experiment onset, without any physical, visual, olfactive and auditive contact. Estrous events were observed twice a day (6:00 and 16:00 h) by trained personnel, during a breeding season of 60 days, and estrous were considered synchronized when detected, within first five days of breeding season. Rams of Santa Inês (n = 2) and Morada Nova (n = 2) breeds were selected based upon reproductive capacity by an andrology exam, and were marked on the externum bone region with a wax and ink (4:1) mixture, and were marked in female lots in order to identify females in [...]

ABSTRACT

An extracelular polysaccharide was produced through microbiology, using the ZSP bacteria isolated in the Industrial Microbiological Laboratory of the Sugar cane Experimental Station at Carpina/UFRPE, Pernambuco, Brazil, presenting exceptional process capacity. The principal monosaccharides present in the ¹soluble fraction were glucose (87.6%), xylose (8.6%), mannose (0.8%), ribose (1.7%), galactose (0.1%), arabinose (0.4%) and the glucuronic acid (0.8%). Due to the high rate of injuries that occur with domestic animals and the search for simple, economical alternatives that would be capable of giving ideal conditions for the healing process, extensive testing was done with the biopolymer produced by sugar cane in animals that had cutaneous wounds, so as to evaluate the reepitelization process. It was observed from the testing results that there was better skin granulation, better infection control, and less healing time, which allowed the conclusion that the biopolymer contributed favorabably in the healing process, and could be used in cutaneous injuries.


Um polissacarídeo extracelular foi produzido por via microbiológica, através da bactéria ZSP isolada no Laboratório de Microbiologia Industrial da Estação Experimental de Cana-de-Açúcar do Carpina/UFRPE, apresentando excepcional capacidade de processo. Os principais monossacarídeos presentes na fração solúvel foram glicose (87,6%), xilose (8,6%), manose (0,8%), ribose (1,7%), galactose (0,1%), arabinose (0,4%) e o ácido glucurônico (0,8%). Devido ao alto índice de traumatismos que acomete os animais domésticos e a busca por alternativas simples, econômicas e capazes de proporcionar condições ideais para cicatrização, foram realizados os testes com o biopolímero produzido a partir da cana-de-açúcar em animais portadores de feridas cutâneas, a fim de avaliar a reepitelização. Observou-se o aumento do tecido de granulação, controle da infecção e diminuição do tempo de cicatrização, permitindo concluir que o biopolímero contribui para o processo cicatricial, podendo ser utilizado em feridas cutâneas.
